Abstract. In Emission Tomography imaging, respiratory motion causes
artifacts in lungs and cardiac reconstructed images, which lead to misin-
terpretations and imprecise diagnosis. Solutions like respiratory gating,
correlated dynamic PET techniques, list-mode data based techniques
and others have been tested with improvements over the spatial activity
